Referring to fig. 1-3, an anti-slip polishing disc according to an embodiment of the present invention includes a surface disc 200 and a plurality of conversion plates 100, wherein the surface disc 200 has a mounting structure 220 for connecting a rotating device to rotate the surface disc 200 to polish an object. In the present embodiment, there are six of the converter plates 100, and six of the converter plates 100 are fixed to the face plate 200 in an annular array around the mounting structure 220.

Specifically, the face plate 200 has a surface 210 facing the polishing object, and the surface 210 is recessed to form a plurality of caulking grooves 230 corresponding to the structure of the conversion plate 100. In this embodiment, there are six of the caulking grooves 230. The depth of the caulking groove 230 is smaller than the thickness of the conversion sheet 100, the conversion sheet 100 is embedded in the caulking groove 230 in an interference mode, so that the conversion sheet 100 can be stably fixed on the face disc 200, the polishing surface 31 of the conversion sheet 100 protrudes out of the surface of the face disc 200, so that the polishing surface 31 can polish articles, and in the polishing process, the conversion sheet 100 is completely fixed relative to the face disc 200, so that the polishing effect is better.

In order to facilitate the removal of the conversion sheet 100 from the insertion groove 230, a through hole 231 is formed at the insertion groove 230, and when the conversion sheet 100 needs to be removed, a tool is inserted through the through hole 231 to push the conversion sheet 100 to be removed from the insertion groove 230.

Referring to fig. 4 to 6, the conversion plate 100 includes a substrate 10, a fixing ring 20, and a polishing layer 30.

The outline of the substrate 10 is substantially the same as the shape of the fixing ring 20, the substrate 10 may be a circular plate, the fixing ring 20 may be a fixing ring, and the edge of the substrate 10 is rounded in order to prevent the edge from cutting the hand.

The substrate 10 is provided with a first positioning structure 11, the first positioning structure 11 may be a positioning pin and/or a positioning hole, the caulking groove 230 is provided with a second positioning structure corresponding to the first positioning structure 11, and the second positioning structure may be a positioning hole and/or a positioning pin, so that the conversion sheet 100 is positioned on the polishing disc and fixed. In order to fix the conversion plate 100 on the polishing disc more stably, it is preferable that the base plate 10 is made of a magnetic material (for example, a magnetic metal material or a magnet, etc., without limitation), and a magnet is provided in the insertion groove 230 to attract the conversion plate 100, thereby further improving the fixing effect of the conversion plate 100, and a receiving groove may be provided in the insertion groove 230 to fix the magnet.

The polishing layer 30 has a polishing surface 31 and a smooth surface 32, the polishing layer 30 may preferably be a hook and loop fastener, and the polishing surface 31 is a hook surface of the hook and loop fastener.

Optionally, when the substrate 10 is placed in the fixing ring 20, the distance between the side surface of the substrate 10 and the inner surface of the fixing ring 20 is smaller than the thickness of the polishing layer 30, so that the edge portion of the polishing layer 30 can be pressed between the side surface of the substrate 10 and the inner surface of the fixing ring 20 by interference fit, thereby fixing the polishing layer 30 on the substrate 10 and making the smooth surface 32 of the polishing layer 30 abut against the surface of the substrate 10, and in addition, since the friction coefficient of the polishing surface 31 of the polishing layer 30 is very large, when the edge portion of the polishing layer 30 is pressed between the side surface of the substrate 10 and the inner surface of the fixing ring 20, the friction force between the polishing surface 31 and the inner surface of the fixing ring 20 is very large, thereby better preventing the polishing layer 30 from separating from the substrate 10, if the polishing surface 31 of the polishing pad is failed, the fixing ring 20 is separated from the base plate 10 by an external force, thereby detaching the failed polishing layer 30 and replacing the new polishing layer 30, which is more convenient and rapid.

In order to further improve the reliability of the grinding layer 30 being fixed, the edge 33 of the grinding layer 30 is coated with an adhesive capable of further fixing the edge of the grinding layer 30 with the fixing ring 20 and/or the base plate 10.

Referring to fig. 7, the present invention further provides a method for manufacturing an anti-drop polishing disc, which includes the following steps:

step 1: providing a dough disk 200 and a conversion sheet 100; a caulking groove 230 corresponding to the structure of the conversion plate 100 is arranged on the face plate 200, and the depth of the caulking groove 230 is smaller than the thickness of the conversion plate 100;

step 2: the grinding piece of the conversion plate 100 is faced outwards and pressure is applied to the conversion plate 100 to move towards the direction of the caulking groove 230 until the conversion plate 100 is embedded in the caulking groove 230 in an interference mode, so that the grinding surface protrudes out of the surface of the face plate 200.

Referring to fig. 8 and 9, the de-conversion sheet 100 is fabricated by:

the method comprises the following steps: providing a base plate 10, a retainer ring 20 and a polishing pad;

step two: placing a polishing surface 31 of the polishing sheet on the retainer ring 20 and placing the substrate 10 on the polishing sheet;

step three: applying a pressure to the substrate 10 moving toward the retainer ring 20 until the edge portion of the polishing layer 30 is pressed between the side surface of the substrate 10 and the inner surface of the retainer ring 20;

step four: and cutting off the redundant part of the edge of the grinding layer 30 to obtain the conversion sheet 100.

In this embodiment, after cutting off the unnecessary portion of the edge of the polishing layer 30, the method further includes:

and coating an adhesive on the edge of the polishing layer 30 so that the edge of the polishing layer 30 is fixed with the fixing ring 20 and/or the substrate 10.
